The 25-year-old left wing-back joins the club as a free agent, bringing valuable experience from spells in France, England and Greece.
A product of the Le Havre and Liverpool academies, Larouci made nearly 50 Ligue 1 appearances for Troyes before gaining experience in English football with Sheffield United and Watford, where he featured 39 times during the 2024/25 season.
The dynamic left-footer spent last season on loan at Greek side Kifisia and has also represented France at youth level before switching allegiance to Algeria, featuring in the squad for the 2024 Africa Cup of Nations.
Larouci becomes Le Mans’ third summer signing after Bilal Brahimi and Louis Mafouta and will wear the No. 76 shirt.
